It is the high-tech, secretive phone designed to repel attacks and even self destruct if compromised.

The Boeing Black phone was specifically built to handle Top Secret information and, it is claimed, has been given to Donald Trump.

However, confusion surrounds which handset the President is actually using.

It's the high-tech, secretive phone given to the incoming president – but it seems President Donald Trump may still being using his unsecured Samsung Galaxy. The Boeing Black phone was specifically built to handle Top Secret information and self-destruct

BOEING BLACK PHONE

The Boeing Black phone encrypts calls and is specifically designed for government agencies and others that need to keep communications and data secure.

The dual-sim phone supports GSM, WCDMA and LTE for high speed data.

It has a 4.3inch screen

The handset also comes with USB , Wifi and Bluetooth.

It will run a secure version of Google's Android software.

And it will self-destruct if someone tampers with it in order to keep Top Secrete data from falling into the wrong hands.

On November 1, Lynn and President Obama were the first two, maybe even the only two, who received a Black Boeing phone, claims Patrick Tucker with Defense One.

Tucker this week contacted the DISA asking if Obama's Boeing Black phone had been handed off to Trump.

But the official's only response was that the phone 'goes with the office of that position'.

Before taking the oath of office on January 20, President Donald Trump was at first believed to have handed over his personal Android phone.

The New York Times reported President Trump swapped his personal phone for a 'secure, encrypted device approved by the Secret Service with a new number that few people possess.'

But it seems the story has since changed.

Six days later, The New York Times published another article that included evidence that the President is still using his Samsung Galaxy.

'Mr. Trump's wife, Melania, went back to New York on Sunday night with their 10-year-old son, Barron, and so Mr. Trump has the television — and his old, unsecured Android phone, to the protests of some of his aides — to keep him company,' reported Maggie Haberman with The Times.

And many are wondering why the President is not using his phone fit for a spy.

The Boeing Black phone is a collaboration between Boeing and the Defense Information System Agency (DISA).

It encrypts calls and is specifically designed for government agencies and others that need to keep communications and data secure.

The phone uses dual SIM cards to enable it to access multiple cell networks and can be configured to connect with biometric sensors and satellites.

And the Department of Defense Information Networks head Lt. Gen. Alan Lynn confirmed the Boeing Black works with 'a large amount of encryption.'

Many Android users know that their smartphones can be hacked at any moment, which makes many security experts worry about Trumps decision to keep his phone close.

The New York Times published an article stating: 'Mr. Trump's wife, Melania, went back to New York on Sunday night with their 10-year-old son, Barron, and so Mr. Trump has the television — and his old, unsecured Android phone, to the protests of some of his aides — to keep him company (Pictured is Trump campaigning in 2016)

'This is a consumer device, and it's going to have security vulnerabilities,' Bruce Schneier, an internationally renowned security technologist, shared in a blog post.

'He's at risk from everybody, ranging from lone hackers to the better-funded intelligence agencies of the world. And while the risk of a forged e-mail is real — it could easily move the stock market — the bigger risk is eavesdropping.

'That Android has a microphone, which means that it can be turned into a room bug without anyone's knowledge. That's my real fear.'

However, experts like Schneier might be able to sleep better at night knowing Trump was just using the Boeing Black phone.

The system works by using the handset to access a remote server on the military's Top Secret JWICS network.

The phone itself just send keyboard, mouse and other signals to the 'real' server.

said Lynn: 'We're not too worried about losing data,' at least not off the phone,' aid Lynn.

He also admitted he thought his boss liked that handset.

'I think he does,' he told Defense One in a November interview.

'Haven't heard any complaints.'

'The phone will be sold primarily to government agencies and companies engaged in contractual activities with those agencies that are related to defense and homeland security,' Boeing says.

It plans to limit the sale of the device to 'approved' buyers.

'The device will be marketed and sold in a manner such that low level technical and operational information about the product will not be provided to the general public.'

Even if approved, buyers will have to sign an agreement agreeing to keep their details of the phone secret.

WHAT COULD BE IN THE PHONE

A researcher from the University of Maryland revealed other features and technology that could be included in President Donald Trump's official phone.

One level of protection is what is called 'security by obscurity.'

Many people presumably had Trump's pre-presidential phone number.

Now, relatively few people will have his new number.

'Trusted Platform Module' is included that notifies authorities if phone has been tampered with.

The phone may only be able to connect with certain predetermined phone and data networks that are regularly screened against intrusions.

Limiting its contact with the internet would be key.

Trump's phone likely has some degree of customization such as a unique operating system.

The apps allowed on the president's phone should be few and limited only to those verified in advance.

Separately encrypting the memory spaces used by each app can boost security further.

Perhaps the phone's microphone and camera could be shut off, and any active Twitter link disconnected, if the phone itself is in the Oval Office, and whenever the president is meeting with members of his national security team.

'Specifically designates and protects as 'proprietary information' the components, hardware, Product Software, applications, functionalities, or internal structure or workings of the Product provided by Seller, including without limitation those that can be obtained by disassembling or opening the Product or its software or components.'

'There are no serviceable parts on Boeing's Black phone and any attempted servicing or replacing of parts would destroy the product.

'The Boeing Black phone is manufactured as a sealed device both with epoxy around the casing and with screws, the heads of which are covered with tamper proof covering to identify attempted disassembly.

'Any attempt to break open the casing of the device would trigger functions that would delete the data and software contained within the device and make the device inoperable.'

Blackberry confirmed the existence of the project in 2015- but refused to reveal any more information.

The FCC filing reveal very little about the phone - other than its shape and the fact it will take two sim cards. The system works by using the handset to access a remote server on the military's Top Secret JWICS network

'We're pleased to announce that Boeing is collaborating with BlackBerry to provide a secure mobile solution for Android devices utilizing our BES 12 platform,' BlackBerry's CEO John Chen said on a conference call held to discuss its quarterly results in 2015.

'That, by the way, is all they allow me to say.'

The Boeing Black device encrypts calls and is aimed at government agencies and others that need to keep communications and data secure.

It uses dual SIM cards to enable it to access multiple cell networks and can be configured to connect with biometric sensors and satellites.

Lynn confirmed the Boeing Black works with 'a large amount of encryption.'

However, he said it was its ability to keep data on servers rather than on the handset that made it attractive.

'There's nothing that lives on the devices,' he explained.

It also reveals that the handset will be completely sealed, and any attempt to open it will destroy the phone and delete all the data on it.
